1 // 创建二维码进行投放 2 $data = array('action_name' => "QR_CARD", 3 // 'expire_seconds' => 1800, 4 'action_info' => array('card' => array('card_id' => "piPuduNg0bM6 Q5hB8rrcK3OXavSE", 5 // 'code' => "198374613512", 6 // 'openid' => "oFS7Fjl0WsZ9AMZqrI80nbIq8xrA", 7 'is_unique_code' => false, 8 'outer_id' => 100), 910 ),11 );12 $result = $weixin->create_card_qrcode($data); 当用户领取门票以后，为其更新座次信息，代码如下。
1 // 更新会议门票2 $data = array(3 'code' => "019538767119",4 'card_id' => "piPuduNg0bM6Q5hB8rrcK3OXavSE",5 'zone' => "C区",6 'entrance' => "东北门",7 'seat_number' => "2排15号",8 );9 $result = $weixin->update_card_meetingticket($data);
最终用户领取到的门票及更新后的门票信息如图16-11所示。
